Point Source Lists
2024 March

The SMC-Last project mapped the Small Magellanic Cloud (SMC) with Spitzer's
Infrared Array Camera (IRAC) at 3.6 and 4.5 um during 2 epochs, once in 2017 
August-September and a second time 2017 November-2018 February.

The 2024 March deposit, SMCLast_PSC_2024Mar.zip, contains of a set of 
6 point source lists. Following the practice of previous programs, a file
with the more reliable sources is the "catalog" file, while a more complete
"archive" also includes less reliable sources. There is one pair of files 
with sources extracted from each of the two observational epochs and a pair 
extracted from the combined mosaics. Files describing the file contents 
"hdr_v7.txt" and the format string "cat_format_string.txt" are also included.
